选项表单标签未使用JavaScript

时间：2019-05-20 19:06:05

标签： javascript jquery html css twitter-bootstrap

因此，当我单击它们时，我有四个按钮，它们都更改了播放器ID上的innerHTML-但我无法使下拉菜单正常工作，而无法将它们用作按钮。

示例：当我单击底部的EXCEL按钮时，它会转换为“测试2”，但是当我更改为“ EXCEL”下拉菜单时也会显示“ Testing 2”，我也希望拥有它但javascript似乎无法读取onchange或我没有正确调用它-有人知道我可能在做错什么吗？希望我能为此提供所有帮助。

var tabButtons = document.querySelectorAll('#options > button');
	  var tabButtons = document.querySelectorAll('#rChoices > option');

	  var player = document.getElementById('player');
	  	  
	  function videoSelect(element){
  		if (element === "word"){
    		player.innerHTML = '<p>Testing 1</p>';
    	}
   		if (element === "excel"){
    		player.innerHTML = '<p>Testing 2</p>';
  		}
   		if (element === "powerpoint"){

尝试使用this.value传递到videoSelect函数，例如onclick="videoSelect(this.value)" select标签内的rChoices。另外，您在第一个选择选项上缺少“ {word}”的option值。您还只需要在onChange标记上使用select，而不需要在所有option标记上使用。

或者，您可以将buttons更新为也包含value="word"等，其值与id相同，然后将this.value传递给您的videoSelect函数，如下所示：好吧，如果想要的话，为了保持一致性。

var tabButtons = document.querySelectorAll('#options > button');
var tabButtons = document.querySelectorAll('#rChoices > option');

var player = document.getElementById('player');

function videoSelect(element) {
  // console.log(element);
  if (element === "word") {
    player.innerHTML = '<p>Testing 1</p>';
  }
  if (element === "excel") {
    player.innerHTML = '<p>Testing 2</p>';
  }
  if (element === "powerpoint") {
    player.innerHTML = '<p>Testing 3</p>';
  }
  if (element === "onenote") {
    player.innerHTML = '<p>Testing 4</p>';
  }
}
